spinocerebellar ataxia with axonal neuropathy

spinocerebellar ataxia with axonal neuropathy

ataxic disorder with polyneuropathy that is related to mutations in a DNA repair gene, tyrosyl-DNA phosphodiesterase.

spinocerebellar ataxia with axonal neuropathy

An autosomal recessive cerebellar ataxia (OMIM:607250) characterised by peripheral axonal motor and sensory neuropathy, distal muscular atrophy, pes cavus and steppage gait (as seen in Charcot-Marie-Tooth neuropathy), with normal IQs.
